The old centre in two hours
From the Trinity Cathedral down to the Psel through every century of the city: Cossack Baroque, Classicism, the sugar barons' Art Nouveau and the Soviet Teatralna Square.
The art and local history museums and the Shchepkin Theatre were damaged in the strike of 13 April 2025 and are only partly open.
- Trinity Cathedral
A smaller copy of St Isaac's, 1901–1914, with paintings by Nesterov and Petrov-Vodkin.
- Church of the Annunciation
Neo-Gothic, 1901–1911, the city's only Catholic church.
- Kharytonenko mansion
The main house of 1890–91, cared for since 2021 by the Hlukhiv reserve and awaiting restoration.
